Abstract
An optical imaging lens may include a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element, and an eighth lens element positioned in an order from an object side to an image side along an optical axis. Through designing concave and/or convex surface of the lens elements, the optical imaging lens may have improved imaging quality, reduced system length, enlarged aperture, and broad field of view while the optical imaging lens may satisfy at least one inequality.
